The present invention relates to suction cleanersin general, and particularly to improvements to be embodied in a suction'cleaner which reduces the over-all height of the cleaner.

, It is an object oi the invention to provide a new and improved suction cleaner. It is mother object `ot theinvention to provide means for arranging the motor and fan chamber side by side and parallel with the cleaner nomic to reduce 1 the over-all height of the cleaner. Another object is to provide an air passage extending rearwardly trom the nozzle along the'upper wall of the cleaner body to the fan chamber. A Ifurther t object is to provide means at the top of the lcleaner body for converting the machinefrom.

an on the floor" cleaner to a machine adapted to create suction for use with dusting tools in oli the iioor cleaning'. Another obiect is to provide a bail-less connection between the handle and cleaner body. whereby when the handle is in low operating position it lies in the plane of the top wall of the cleaner to permit operation of the cleaner under furniture having low iioor clearance. Other objects and advantages oi the invention will appear in the speciiication anniA drawings wherein:

The suction cleaner herein disclosed comprises `V'a casing Il having a tlat top wall Il curved downwardly at its forward end to form a nozzle l! provided with front and rear surface contacting lips il and Il, respectively.l Supporting the casing Ilis a base or frame Il having a top wall il from which upstands an arcuate wall I'I having its upper end nested in jan arcuate recess il delined in the casing il tos'upport the latter.

An air passageway` It extends upwardly and rearwardly from the nozzle lips as shown in Figure 4 and rearwardly along the right side of the cleaner as viewed in Figure 5 and terminates at the ianeye 22 in the top wall It of the base il. The air passageway is defined at its top by the top wall Il of the casing Il, and at its bottom by the top wall II of the casing- Il. The bottom wall Il ofthe air passageway Il extends upwardly and rearwardly from the rear nomic lip Il as indicated at 25 and then in a horizontal plane as vair passageway 2l is deilned by the arcuate wall, y

I1 which has a semi-circular portion il outlining the rear end o! the air passageway adjacent the tan eye 22, and then extends forwardly and is ared outwardly as shown at Il to the rear nozzie lip I4, the proiecting height oi the side wall I1 being gradually reduced as outlined at Il to gradually merge into the surface of the downwardly curved portion of the bottom wall Il of the air passageway.

Included in the base 'Il is a fan chamber I5 defined at its top by the top wall il of the base Il and at its sides by an arcuate wall 38 depending from the toplwall ii. The side wall 3i has a substantially circular portion il and diverges towards the rear oi the base li. as indicated'at 31, to form the side walls Il of the exhaust passage 39 which terminates at Il along the central longitudinal axis of the cleaner. The bottom of the fan chamber isjclosed by a plate li provided with a marginal' recess 42 to receive the lower edge Il of the fan chamber wall 3l and a iiange N depending from the lower Ywall l5 of the base Il defining the outlet of the exhaust passageway 3|. l

A plurality of screws ll are provided to removably secure the bottom plate 4i to the ian chamber side wall It. The plate Il is formed with a cylindrical seat Il which serves to support the fan shaft bearing Il. Secured to the plate ll by means of rivets l2 is a pressed metal member I3 which houses the remaining portion of the fan shaft bearing Il. Carried by the bearing Il is a vertically mounted fan shaft I4 to which is attached a suction creating ian Il comprising spaced blades Il mounted upon the fan back 5l. The back ot the ian is provided with a peripheral depending iiange Il which extends into a circular channel II formed in the plak li to prevent leakage of dirt-laden air into the bearing li The hub portion Il of the fan is dish shaped. as indicated at Il. to accommodate the bearing li to thereby aid in reducing the overall height of the cleaner.

Supported on the ian shaft M is a pulley i2 `i'orabeltllextenrlingthroughanopeningin the wallot the air passageway 2l and is arranged in an annular recess Il in an agitator Il mounted v in the nozzle l! for contacting the surface undershown at 2| to the ian eye i2.
